Power circuit and cable requirements

A power circuit (see table below) must be provided for connection of
the unit. This circuit must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage breaker.

When using residual current operated circuit breakers, be sure to use
high-speed type circuit breakers of maximum 30 mA that can handle
higher harmonics.

Point for attention regarding quality of the public electric power
supply

This equipment complies with EN/IEC 61000-3-12

(1)

 provided that

the short-circuit power S

sc

 is greater than or equal to 1025 kVA at the

interface point between the user's supply and the public system.

It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with a
short-circuit power S

sc

 greater than or equal to 1025 kVA.

Above indicated value is the most stringent value. Refer to databooks
for specific product-data.

Be sure to install a main switch for the complete system.

8.4.

General cautions 

Make sure to connect the power source wire to the power source
terminal block and to clamp it as shown in 

figure 21

, chapter

"Field line connection".

As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.

Keep power imbalance within 2% of the supply rating.

Large imbalance will shorten the life of the smoothing
capacitor.

As a protective measure, the product will stop operating and
an error indication will be made, when power imbalance
exceeds 4% of the supply rating.

Only proceed with wiring work after switching off all power
sources.

Always ground wires. (In accordance with local regulations.)

Do not connect the ground wire to gas pipes, sewage pipes,
lightning rods, or telephone ground wires. This may cause
electric shock.

Combustion gas pipes: can explode or catch fire if there is a
gas leak.

Sewage pipes: no grounding effect is possible if hard plastic
piping is used.

Telephone ground wires and lightning rods: dangerous when
struck by lightning due to abnormal rise in electrical potential
in the grounding.

This unit uses an inverter, and therefore generates noise, which
will have to be reduced to avoid interfering with other devices.
The outer casing of the product may take on an electrical charge
due to leaked electrical current, which will have to be discharged
with the grounding.

Be sure to install an earth leakage breaker. (One that can
handle higher harmonics.)
(This unit uses an inverter, which means that an earth leakage
breaker capable of handling high harmonics needs to be used in
order to prevent malfunctioning of the earth leakage breaker
itself.)

Earth leakage breakers which are especially designed for
protecting ground-faults must be used in conjunction with main
switch and fuse for use with wiring.

This unit has a reverse phase protection circuit. (If it operates,
only operate the unit after correcting the wiring.)

Power supply wires must be attached securely.

If the power supply would have a missing N-phase or a mistaken
N-phase, equipment will break down.

Make sure that all wiring is secured, the specified wires are
used, and no external forces act on the terminal connection or
wires.
Improper connections or installation may result in fire.

When wiring the power supply and connecting the remote
controller wiring and transmission wiring, position the wires so
that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric
shocks, fire, or the overheating of the terminals.

NOTE

The wiring diagram only applies to the outdoor
unit

When using the option adaptor, refer to the
installation manual

Refer to the installation manual on how to use
BS1~BS5 and DS1, DS2 switch

Do not operate the unit by short-circuiting
protection device S1PH

NOTE

Use copper conductors only.

For connection wiring to the central remote
controller, refer to the installation manual of the
central remote controller.

Use insulated wire for the power cord.
